Hello Everyone!

Wondering if anyone has expertise in Algae Photobioreactor facades? Here is a product: https://cellparc.com/

My basic understanding is that they produce heat and biogas (as well as providing shade and some thermal value.)  However, I am not clear on the GHG balance benefit, so to speak.  I cannot determine if the... Read more

Hello friends,

We are looking for recommendations for solar photovoltaic consultants to support one of our projects.

The results from the "CogFx" study are compelling, showing that people in environments with low VOCs and low ambient CO2 levels score higher on tests of cognitive function.  Specifically, they show that providing 40cfm of outdoor air per (actual live) occupant results in significantly higher scores than even the "Enhanced Ventilation" scheme...
